Code examples

Python (OpenAI SDK)

python

# pip install openai
from openai import OpenAI

client = OpenAI(
    api_key="csky_YOUR_KEY",
    base_url="https://centrosky.com/v1"
)

response = client.chat.completions.create(
    model="auto",
    messages=[{"role": "user", "content": "Hello!"}]
)

print(response.choices[0].message.content)

JavaScript / Node.js

javascript

// npm install openai
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "csky_YOUR_KEY",
  baseURL: "https://centrosky.com/v1"
});

const r = await client.chat.completions.create({
  model: "auto",
  messages: [{ role: "user", content: "Hello!" }]
});

console.log(r.choices[0].message.content);

curl

bash

curl https://centrosky.com/v1/chat/completions \
  -H "Authorization: Bearer csky_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "auto",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Already using OpenAI?

Just change two lines. If your app already uses the OpenAI SDK, swap api_key and add base_url. Everything else stays the same — your prompts, your logic, your error handling. CentroSky is a drop-in replacement.
